FLUSHING DEVICE FOR WATER-CLOSE'IS.

Specification of Letters Patent.

Patented Dec. 30, 1913.

Application filed May 28, 1912. Serial No. 700,337.

To all whom it may concern:

Be it known that I, PHILIP HAAS, citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Flushingv Devices for Water-Closets; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the artto which it appertains to make and use the same. 7

My present invention relates to the class of automatic devices for flushing water closets and consists in an improved construction of valves for controlling the flushing current passing therethrough.

In the drawings I have shown thebest form in which I have contemplated embodying my said invention and the same is described in the following description and claims.

In the drawings, Figure 1 is a view in elevation partly in section of my improved valve. Fig. 2 is a horizontal section on line 22, Fig. 1. Fig. 3 is a par tial vertical section. Fig. 4 is a vertical section on line 44, Fig. 1.

In these figures A is the main body or casing in which are the presure chamber a, the tank chamber a connected with the tank or reservoir (not shown) the inlet chamber a and the outlet chamber a". The chamber a is closed by a cap A and the casing is provided with means, comprising in this instance threaded portions, whereby the other chambers can be connected respectively with the water supply, the tank and a pipe leading to the bowl. The pressure chamber is separated from the tank chamher by a partition 6 and adjacent to the said partition is connected with theoutlet chamber by an opening 22 The inlet chamber is separated from the tank chamber by a partition 6 in which there is anopening 6*.

Within the chamber a I locate a piston B which has connected therewith either in tegrally or otherwise a valve B. To this valve a rod 7) is secured by a threaded con- The outer end of this rod or bar is provided with a valve 0. This valve comprises the disk 0, the

disk 0" and the diminishing body 0'. The periphery of the disk o is provided with cuts or notches 0 so that water may pass freely from one side of the same to the other in either direction. The inner face of the disk 0 constitutes a valve for the purpose of enabling the water pressure to additionally secure the valve opening in the partition Z) separating the tank chamber a and the inlet chamber a This body of this valve is connected to the disk and valve 0 and to the rod 6 and is cut away on three sides, the removed portions diminishing toward the disk 0. This valve body is fitted to and works in the opening 6* of the partition 6 The valve C is normally in position with the disk 0 seating against the partition 6, cutting off all influx of water from the inlet chamber a and when it is in this position the piston B will be at the opposite or left hand end of'the chamber a.

The main body A has upon one side of the same a vertically disposed projection D. This projection is hollowed out to form chambers d, d connected by a short passage (Z Upon the main body there are also two broad webs (5 at one on each side of the projection D and connected therewith. The chamber cl is closed at its upper end by the cap In the chamber (Z there is located a valve E having an upwardly extending stem 6. The upper end of this stem engages the guiding recess (Z in the cap (Z A spring 6' around the stem has its upper end bearing against the cap and upon the upper face of a nut 6 or upon the upper side of the valve E for moving the valve downward and maintaining it in its lowermost or closed position. Below the valve there is a depending bar or rod (Z which may be an extension of the valve stem or a separate device secured to the valve. This rod is of such size as to move freely in the passage 0Z The lower end of the chamber cl is closed by a stufling box through which a rod E passes and may be moved. Within the chamber (Z the rod E connects with a valve E adapted to be moved upward and close the lower end of the passage (Z The upper end or side of this valve is provided with a pin or short section of rod 6 which may be a continuation of rod E or a separate part secured to the valve. This pin 0 is of such size as to loosely engage a recess d in the lower end of the rod 6 The rod E is so arranged with reference to the bowl and its seat that pressure upon the seat will, through means not shown,

raise the rod E and lift the valve E'to such an extent as to raise the rod 6 out of the passage (Z This movement will also move the valve E upward and close the lower end of passage (Z By reference to Fig. 2 it will be seen that there is a passage 9 opening out of the inlet chamber a This passage is preferably located within the web (i and discharges into the chamber (Z. In the web (Z is another passage g connecting the passage (Z with the rear or left hand end of the chamber a. The chamber (Z is also connected by a short passage 9 with the outlet chamber. This raising of the rod E permits water to flow through the passage 9 into the'chambe'r (Z and from thence into passage 6Z2 and through passage g into the chamber a in rear of the piston B. This moves the connected valve B to close the opening connecting the pressure chamber and the tank chamber. As the piston begins to move the valve or disk 0 leaves its seat upon the partition I), permitting water to flow over the reduced portions of the body 0 into the tank chamber. This flow is small at first as the current flows first over the higher or larger parts of the reduced portion and gradually increases until the valve B is seated. The movement of the piston and valve is comparatively rapid and but little water passes from the tank chamber before the valve B closes the connection of the tank chamber with the outlet. When the valve B is fully seated it causes the incoming current to flow upward into the tank until the pressure therein equals that of the water supply. Then the seat is relieved from pressure the valve E is depressed by the spring 6 and cuts off the pressure of the water supply upon the piston B and the rod 41 descends into the passage d This permits the pressure upon the face of the valve B to force the piston B backwardly and to expel the water in the chamber av out by way of the passage g through the passage (Z around the rod (1? into the chamber (Z depressing the valve E and the rod E. From the chamber d the water flows through the passage g into the outlet. As the valve B leaves its seat the ater from the tank chamber and tank flows out through the opening in partition 6 into the chamber a, thence through the opening Z2 into the outlet chamber and to the bowl. As the rod 6 so nearly fills the passage (Z the outward flow of the water in the pressure chamber is comparatively slow. The greater reduced portions of the body 0 of the valve C being in the opening 6 in the partition 6 water from the inlet chamber and supply pipe flows out and unites with the current from the tank. The duration oftheflow" for flushing the bowl depends on the distance between the valve close this opening the flow of water will be so far diminished that the siphon action emptying the bowl will cease and only water enough to fill the trap and seal the bowl will flow into the latter, before the disk 0 will seat itself against the partition I) closing the opening therein: The flow of water will then be entirely out OE and all the parts will have returned to normal position.

What I claim and desire to secure by Letters Patent is:'

In a flushing valve, the combination with a casing provided with a pressure chamber a tank chamber, an inlet chamber, and an outlet chamber, a partition separating the inlet and tankchambers, a partition separating said pressure and tank chambers,each of said partitionsbeing provided with an aperture therein, and said casing'being provided with an aperture connecting the pressure chamber and the outlet chamber, a piston in the pressure chamber, a' valve connected therewith for closing the aperture in the adjacent partition, a valvefor closing the aperture in the other of said partitions, provided witha part extending through the aperture therein, said part having cutaway portions for gradually diminishing the flow through said aperture before the seatingof' said valve to restore the water seal, means for establishing a connection from the inlet chamber to the pressure chamber in rear of the piston therein, and adjustable devices positively connecting said valves for Copies of this patent may be obtained for five cents each, by addressing the 'Coinniissioner'of Fatents, Washington, I).
